EDWARD L. DELANY, OF BROOKLYN, NEW YORK.

FLUSH-TAN K FOR WATER-CLOSETS.

To all whom it may concern:

Be it known that I, EDWARD L. DELANY, a citizen of the United States, residing in the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful F lushT ank for VVatenClosets, of which the a the invention, but the construction therein following is a specification.

This invention relates to flush tanks for water-closets, and, more particularly, to those of the low-down type. In tanks of this character, the top or cover is exposed to view and has, in the past, been generally secured to the body of the tank by means of screws passed through the top or cover and threaded into the walls of the tank. This is the general construction in wooden tanks and in some metal ones, although, in the maj ority of the metal, composition or porcelain tanks, the cover merely rests loosely upon the top of the tank and may be lifted off at will.

In those. tanks where the screws project above the top of the tank, they are not only unsightly, but preclude the setting of bottles and other toilet articles upon the tank. In cases where the cover is laid on loosely, there is a tendency of'the tenant to lift off the cover, partly through curiosity and frequently in an endeavorto repair. the sensitive mechanism incased within the tank. Moreover,it is not unusual for children to tamper With loose covers, and, in instances where the tank is set unusually low, a person sitting too far back on the seat may inadvertently displace the cover.

With the foregoing, and other, disadvantages in mind, the object of the present invention is to so construct the tank that the cover thereof is locked in place thereon by normally invisible or concealed means and in such manner that only such persons as are familiar with its construction can release the cover, through deliberate manipulation of the parts, to allow of the removal thereof for repairs.

From a more specific standpoint, the invention is particularly adapted for composition, cast or porcelain tanks, the cover and side Walls of the tank being so formed as to interlock or interfit with one another, concealed means being provided for locking the cover and walls in such interlocked or interfitted relation. Moreover, the results specified are accomplished'in a simple, ellicient and economical manner.

Specification of Letters Patent.

Patented Nov. 4, 1919'.

Application filed December 7, 1917. Serial No. 205,950.

Features of the invention, other than those adverted to, as well as the advantages thereof, will be apparent from the follow ing detailed description when read in conjunction with the accompanying drawings.

In the accompanying drawings I have illustrated one practical embodiment of shown is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure l is a perspective view of the tank, partly in section, showing the preferred manner of locking the top or cover in place.

Fig. 2 is a fragmental underneath plan view of a portion of the tank, showing the cover securing means locked in place, and

Fig. 3 is a fragmental elevation of the back of the tank.

Referring to the drawings, A designates the body of thetank which is in the form of a receptacle adapted to house the usual float-controlled valve and releasing mechanism, neither of which is shown as it forms no part of the present invention. The tank may be of any shape, form or proportions, and may be suitably ornamented as desired, but is here shown as of simple, rectangular configuration, in the interest of clearness. The tank is provided with a cover B adapted to close the top thereof. Both the tank and cover may be formed from wood, composition, porcelain, or any other material desired.

In order that cover B and tank A may be detachably assembled, there is provided, preferably along the front wall of the tank, a rabbet or channel a, which extends along the inner face of the front wall and near the upper edge thereof. lVith this channel is adapted to cooperate a flange Z2 formed upon cover Bin such manner that, when the cover is in the position shown in Fig. 1, the flange 6 of the cover will interlock with the channel rabbet a of the tank ant lifting of the cover from the tank is precluded, unless said cover is so manipulated as to disengage the interlocked elements.

It will appear that, in order to disengage the interlocked elements, it will be neces' and this means is preferably in the form of one or more anchor rods C, one of whlch 1s here shown in the interest of clearness.

Anchor rod C extends vertically up the back" of the tank and eXteriorly thereof, the rod being positioned in a vertical channel a formed in the back wall of the tank, so that the'rod will be set in from the plane of the back of the tank and will not interfere with the positioning of the tank tight against a wall. Rod O is provided with a hookshaped portion-0 at its upper end, which hook-shaped portion is adapted to project into a pocket 6! formed in cover B, and, through the cooperation of the hook and pocket, rod C is secured to the: cover in a manner which will be apparent. The lower end of rod C projects beneath the bottom of the tank and is provided with a slot 6, with which is adapted to cooperate a wedge E operating against a washer plate F which bridges channel a" and through which rod C is passed, said construction being best shown in Fig. 3. 1

The assembling of the parts and their mode of operation will be apparent, it being manifest that, after flange Z) is interlocked with channel a, anchor rod C is clamped down tight by forcing in thewedge E. This operation may be accomplished either before the installation of the tank or thereafter, since the channel a in the back of the tank allows of sufficient clearance for the ready insertion of the rod.

Low-down tanks of the character scribed are invariably placed with their backs tight against a wall, and this fact makes it impossible to shift the cover rearwardly to allow of the disengagement of flange 6 from channel a, as theback edge of the cover or top B will rest against the wall of the building However, the releasing of the flange will be rendered absolutely impossible until rod C is released. Anchor rod 0 will hold the cover down in tight frictional engagement with the end walls of the tank, so that the structure will be rigid and no rattling can occur.

drive out wedge E, whereupon rod C is released and the cover may be removed In order that the joint between the cover and theupper edge of the tank may be concealed, the sides and front edge of the cover are preferably provided witha depending flange b.

In the preferred embodiment of-the invention shown, the interlocking portions of the cover and tank are shown as extending from one end of thetank to, the other, but, in practice, flange b may be in the form of one or more fingers which cooperate wlth a like number of sockets a in the wall-of the tank. The invention, broadly, contemplates interlocking or interntting cooperating parts .de- I When it is'desired to :remove the cover, it is only necessary to on the tank and cover, and thereafter lock. ing such parts against disengagement from one another, whereby thecover is precluded from disengagement from the tank.

In adapting the invention to difierent forms of tanks, the construction of the ining a tank, a cover therefor, interlocking flanges on the tank and'the cover, adapted to be moved into and out of interlocking relation by pivotal movement of the cover, and means for locking the'cover against pivotal movement when in a position to seal thetank. p

2. A structure of the class described embodying a tank, a cover therefor, a member at the top edge of the front wall of the tankadapted to interfit with a cooperating member near the front edge of the cover, and means concealed rearwardly of the back wall of the tank for locking the cover in place.

3. A structure of the class described embodying a tank provided at its top with an interlocking member, a cover provided with an interlocking member adapted to cooperate with the interlocking member on the tank, means secured to the back portion of the cover and extending downwardly at the back of the tank, and a device for securing said means to the body of the tank, whereby the cover is locked in place.

4,. A flush tank for water-closets embodying a tank, a cover therefor, interlocking flanges on the tank and the cover, adapted to be moved .into and out of interlocking relation by pivotal movement of the cover,.

the cover against pivotal movement when in a position to seal the tank.

5. A structure of the class bodying a tank, a cover therefor, a locking with said member and the bottom of the- .and normally concealed means for locking,

described emmember having a portion seated within the cover of the tank, and means, cooperating tank for tightly clamping the cover in r in proximity to the top of said groove, and

a locking member traversing the groove, one end of which fits into said socket and the other end of which is provided with means for securing the locking member in fixed relation to the tank.

7. A structure of the class described embodying a tank, one of the walls of which is provided on its outer surface with a substantially narrow groove, and one of the walls of which is provided near its upper edge with an offset, a cover for the tank provided with a concealed socket in proximity to the top of said groove and at one of its edges an ofl-set cooperating with the ofl-set on the wall of the tank, and a looking member traversing the groove, one end of which takes into said socket and the other end of which is provided with means for securing the locking member in fixed relation to the tank.

8. A structure of the class described embodying a tank, the top front end of which is provided with a flange, a cover for the tank having an interfitting flange cooperating with said flange on the tank, and a rod extending vertically of the tank and having a hook at its upper end fitting into a depression in the cover of the tank, the other end of said rod extending below the tank and being provided with a slot and wedge, whereby the rod may be tightened and the cover locked against inadvertent disengagement.

9. A structure of the class described embodying a tank, the top front end of which is provided with a flange, a vertically extending groove in the outer face of the back Wall of said tank, a cover for the tank having an inter-fitting flange cooperating with said flange on the tank, and a rod traversing the specified groove and having a hook at its upper end fitting into a depression in the cover of the tank, the other end of said rod extending below the tank and being provided with a slot and wedge, whereby the rod may be tightened and the cover locked against inadvertent disengagement.

In testimony whereof I have signed my name to this specification.
